With the techniques in this blogpost, 32GB disk proved sufficient
- 32GB disk with 30.10 x 109 bytes
- 18.5GB land-grab with 19.97 x 109 bytes
- 10GB actually used and I can’t make do with less

— C:\ProgramFiles\WindowsApps: 4GB. See to delete stubborn WindowsApps folders
— c:\windows\serviceProfiles: 4GB. Somehow resolved, perhaps by builtin StorageSettings screen
— c:\recovery. Unsafe to delete. See https://superuser.com/questions/1517095/deleted-usmt-ppkg-nothing-works-anymore-windows-10
— c:\windows\software_distribution\download ? safe to delete
Was 300MB on Day 1 but grew to 8GB on Day 2
— c:\windows.old and $WINDOWS.~BT .. I feel I have never needed to go back to previous install of windows
Safest way to delete windows.old is via Settings -> Storage -> TemporaryFiles.
I see no need to delete this static folder. It is similar to my landGrab files.
— WindowsApps folder ? not worth optimizing. Quite risky.
— c:\windows\winSxS ? See tips in https://docs.microsoft.com/en-us/windows-hardware/manufacture/desktop/clean-up-the-winsxs-folder
— C:\hiberfil.sys? safe to get rid of, using the command found on google
— c:\pagefile.sys + swapfile.sys? Safe to delete but may hurt performance. These are considered virtual memory files
- set too small, and it could cause instability, but it’s crucial to experiment and find out how bad. In 2020 I let it automatically shrink to 200MB, and experienced browser crashes only one the a95, never on the acer299.
- set too big, and it could lead to winUp on rampage. So I don’t want the initial size vs max size to differ
- Given 8GB RAM, Online recommendations range from 1.25 GB to 12GB, but the win10 system recommends [on the virtual memory screen] 1900MB
